Whether you are using Apache or Nginx as your web server, this guide will walk you through the complete setup process. Follow this step-by-step tutorial to get started, even if you’re a beginner.

What is Roundcube Webmail?

Roundcube Webmail is an IMAP-based, open-source webmail client written in PHP. It provides a user-friendly interface similar to desktop email clients, making it an excellent option for those who prefer managing emails through a browser. Key features include:

  • Email management (read, send, reply, forward, and organize emails).
  • Address book integration.
  • Support for plugins to extend functionality.
  • Mobile-friendly design.

Prerequisites for Roundcube Webmail Setup

Before diving into the installation process, ensure you have the following:

  • A Linux server (Ubuntu 20.04 or newer recommended).
  • Apache or Nginx installed.
  • PHP version 7.4 or higher.
  • MariaDB or MySQL database server.
  • Access to DNS records for your domain.

Let’s get started with the installation and configuration process!

Step 1: Update and Upgrade Your Server

It’s essential to start by ensuring your server is updated. Run the following commands to update your package manager and upgrade installed packages:

$ sudo apt update  
$ sudo apt upgrade -y

Step 2: Install Required Dependencies

For both Apache and Nginx, install PHP and required modules:

$ sudo apt install php php-cli php-mbstring php-xml php-mysql php-curl php-zip unzip -y

You’ll also need composer for dependency management:

$ sudo apt install composer -y

Step 3: Install Apache or Nginx

Install Apache:

To set up Roundcube with Apache, install it with the following command:

$ sudo apt install apache2 -y

Ensure Apache is running:

$ sudo systemctl start apache2  
$ sudo systemctl enable apache2

Install Nginx:

For Nginx users, install it with:

$ sudo apt install nginx -y

Start and enable the Nginx service:

$ sudo systemctl start nginx  
$ sudo systemctl enable nginx

Step 4: Set Up a Database for Roundcube

Roundcube requires a database to store user settings and data. You can use MariaDB or MySQL.

Install MariaDB:

$ sudo apt install mariadb-server -y

Secure the MariaDB installation:

$ sudo mysql_secure_installation

Create a Roundcube Database:

Log into the database:

$ sudo mysql -u root -p

Run the following SQL commands to create a database and user for Roundcube:

CREATE DATABASE roundcubemail;  
CREATE USER 'roundcubeuser'@'localhost' IDENTIFIED BY 'strongpassword';  
GRANT ALL PRIVILEGES ON roundcubemail.* TO 'roundcubeuser'@'localhost';  
FLUSH PRIVILEGES;  
EXIT;

Step 5: Download and Install Roundcube

Visit the Roundcube official website and get the latest version of Roundcube. Alternatively, download it using the command line:

$ wget https://github.com/roundcube/roundcubemail/releases/download/1.6.9/roundcubemail-1.6.9-complete.tar.gz

Extract the downloaded file:

$ tar -xvzf roundcubemail-1.6.9-complete.tar.gz

Move the files to your web server’s root directory:

$ sudo mv roundcubemail-1.6.9 /var/www/roundcube

Set appropriate permissions:

$ sudo chown -R www-data:www-data /var/www/roundcube  
$ sudo chmod -R 755 /var/www/roundcube

Step 6: Configure Apache for Roundcube

Create a new configuration file for Roundcube:

$ sudo nano /etc/apache2/sites-available/roundcube.conf

Add the following configuration:

<VirtualHost *:80>  
    ServerName yourdomain.com  
    DocumentRoot /var/www/roundcube  
    <Directory /var/www/roundcube>  
        Options FollowSymLinks  
        AllowOverride All  
        Require all granted  
    </Directory>  
    ErrorLog ${APACHE_LOG_DIR}/roundcube_error.log  
    CustomLog ${APACHE_LOG_DIR}/roundcube_access.log combined  
</VirtualHost>

Enable the site and restart Apache:

$ sudo a2ensite roundcube.conf  
$ sudo systemctl restart apache2

Step 7: Configure Nginx for Roundcube

For Nginx users, create a new configuration file:

$ sudo nano /etc/nginx/sites-available/roundcube

Add this configuration:

server {  
    listen 80;  
    server_name yourdomain.com;  
    root /var/www/roundcube;  
    index index.php index.html;  
    location / {  
        try_files $uri $uri/ /index.php;  
    }  
    location ~ \.php$ {  
        include snippets/fastcgi-php.conf;  
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;  
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;  
        include fastcgi_params;  
    }  
    location ~ /\.ht {  
        deny all;  
    }  
}

Enable the configuration and restart Nginx:

$ sudo ln -s /etc/nginx/sites-available/roundcube /etc/nginx/sites-enabled/  
$ sudo systemctl restart nginx

Step 8: Complete Roundcube Installation via Web Interface

  1. Open your browser and navigate to http://yourdomain.com/installer.
  2. Follow the on-screen instructions to verify dependencies and configure the database.
  3. Enter the database details created earlier (e.g., roundcubemail, roundcubeuser, and your password).
  4. Complete the installation process and remove the installer directory for security:
$ sudo rm -rf /var/www/roundcube/installer

Step 9: Configure DNS for Webmail

To access Roundcube via webmail.yourdomain.com, set up a DNS A record pointing webmail to your server’s IP.

Step 10: Secure the setup with HTTPS

Use Let’s Encrypt to secure the connection. Install Certbot:

$ sudo apt install certbot python3-certbot-apache -y

For Apache:

$ sudo certbot --apache -d yourdomain.com -d webmail.yourdomain.com

For Nginx:

$ sudo apt install python3-certbot-nginx -y  
$ sudo certbot --nginx -d yourdomain.com -d webmail.yourdomain.com

Ensure the certificate is renewed automatically:

$ sudo systemctl enable certbot.timer

Troubleshooting Common Issues
